Macintosh HD taking up too much disk space

I have a MacBook Pro running on Mojave 10.14.6 but I can't update it because the Macintosh HD is taking up so much disk space. I've taken everything I can off my computer and it still hasn't helped. So two part question:

  1. What is Macintosh HD? I Googled but didn't really understand.
  2. What can I do to make this take up less disk space?


Thanks in advance!

MacBook Pro 13″, macOS 10.14

Macintosh HD is the default name for your internal hard drive.

On the hard drive will be the macOS Mojave system and all your personal info

such as documents, photos, movies, apps etc etc.


You can get an overview of this if you click on the top left of the screen

and selecting About This Mac and click on Storage

See the screenshot below, my disk has been renamed SSD APFS.



If you could do the same and post back a screenshot as above would be helpful.


Quite often the information in Storage is wrong and can sometimes be corrected by rebuilding

the Spotlight index.


How to rebuild the Spotlight index on your Mac – Apple Support


Open System Preferences> Spotlight> Privacy

Move the Macintosh HD (or the name you gave your disk) in to the Privacy panel.


Quit System Preferences.


Open System Preferences> Spotlight> Privacy highlight Macintosh HD and press the minus button.


The mac will start rebuilding the Spotlight index.


Check by clicking on Spotlight in the menubar and enter a word, if it is indexing you should see a progress bar.


You can also use the Terminal app in your Applications> Utilities folder to force Spotlight to reindex.


Open Terminal.


Enter this command,


sudo mdutil -E <drag the icon of the drive you want to reindex here>

(make sure there is a space after the E.)


enter your Password.

(what you type will not be repeated on screen)

press Return


Terminal will confirm if indexing is enabled on the Volume/ drive and after a few seconds 

Spotlight should begin reindexing.


To confirm click on the Spotlight icon in the menubar, type in a word, if there is a progress bar, Spotlight is indexing.


If re-indexing has not solved your problem then run this app, https://www.omnigroup.com/more

this will give an accurate account of the storage used. When the app has created its overview you can look at

the Users folder in the output and see what each user has stored, you can then delete files from there.

Do not delete any files or folders in any System or Library folders or any files you do not understand.


If you can get back with the results then we can see if we can move forward.

What mac, model and year do you have and which OS would you like to upgrade to?

From the last screenshot you posted you have only 3.78GBs of free space on your mac.

Your mac is running critically low on free space and may be in danger of locking

up and becoming unusable.

It is generally accepted that you keep no less than 20GBs of free space on the mac so it can do

its housekeeping and remain functional.


You said earlier you have taken off everything you can on your mac, is this true it does not look like it.

If you have copied files over to an external hard drive you then need to delete the original files from your mac.


Movies, images and music often take up the most room so start there.
